Title: 2006 PT 525 Vicksburg transmission fluid
Post by: rkevincarson on January 22, 2023, 02:31:26 PM

Was hoping someone had some pictures or drawing of where to access the fluid fill location for the Allison 4000MH.  The access in the closet is just the top of the engine.  Hate to waste a bunch time if someone knows how to get to it.   Appreciate any help.

On our coach, a 2004 Marquis Sapphire, all engine fluids' fill points are accessible by opening the rear door over the engine.  That includes radiator coolant, engine oil, transmission oil, and power steering oil.

our 06 pt was very difficult to service trans if you have a pump you can pump the fluild or you can left the floor in the bedroom but I liked the pump with hose.
